Diagnosis Procedure

Regarding Wiring Diagram information, refer to "WIRING DIAGRAM ".

1. CHECK A/T SHIFT SELECTOR (PARK POSITION SWITCH) INPUT SIGNAL 
   1. Turn ignition switch OFF.
   2. While pressing the ignition knob switch, check voltage between Intelligent Key unit harness connector M70 terminal 39 and ground.

      Connector	Terminals		Condition	Voltage (V) (Approx.)
      	(+)	(-)
      M70	39	Ground	Selector lever is in "P" position	Battery voltage
      			Other than above	0

      Is the inspection result normal? 

      YES: Replace Intelligent Key unit. Refer to "REMOVAL AND INSTALLATION ".

      NO: GO TO 2

2. CHECK A/T SHIFT SELECTOR (PARK POSITION SWITCH) POWER SUPPLY CIRCUIT 
   1. Disconnect A/T shift selector (park position switch) connector.
   2. While pressing the ignition knob switch, check voltage between A/T shift selector (park position switch) harness connector M203 terminal 5 and ground.

      5 - Ground: Battery voltage.

      Is the inspection result normal? 

      YES: GO TO 3

      NO: Repair or replace harness or ignition knob switch.

3. CHECK A/T SHIFT SELECTOR (PARK POSITION SWITCH) 

   Check continuity between A/T shift selector (park position switch) terminals 5 and 6.

   Component	Terminals		Condition	Continuity
   A/T shift selector (park position switch)	5	6	Selector lever is in "P" position	Yes
   			Other than above	No

   Is the inspection result normal? 

   YES: GO TO 4

   NO: Replace A/T shift selector (park position switch).

4. CHECK A/T SHIFT SELECTOR (PARK POSITION SWITCH) CIRCUIT 
   1. Disconnect Intelligent Key unit connector.
   2. Check continuity between Intelligent Key unit harness connector (A) M70 terminal 39 and A/T shift selector (park position switch) harness connector (B) M203 terminal 6.

      39 - 6: Continuity should exist. 

   3. Check continuity between Intelligent Key unit harness connector (A) M70 terminals 39 and ground.

      39 - Ground: Continuity should not exist.
